WebTherefore, this buffer would only be effective at a range of plus or minus one from 4.74, so about 3.74 to approximately 5.74. The ammonium cation has a pKa value equal to 9.25 at 25 degrees Celsius. Therefore, the ammonium-ammonia buffer is effective plus or minus one of this pKa value, so approximately 8.25 to 10.25. WebA buffer (or buffered) solution is one that resists a change in its pH when H + or OH – ions are added or removed owing to some other reaction taking place in the same solution. Buffers do so by being composed of certain pairs of solutes: either a weak acid plus its conjugate base or a weak base plus its conjugate acid.
